Abstract (en)

There is proposed is a bending device which has a simple structure, easily performs a control and provides a high degree of freedom in bending. The bending device is provided with a positioning jig (6) with a clearance hole (4) formed therein for passing a material (1) to a bending jig (34) for contacting an outer periphery of the material supplied from the positioning jig (6). A rotary body (18) is rotated by a rotating drive source (22) coaxially with the material passed through the clearance hole (4) in the positioning jig (6). The bending jig (34) is attached to a member (30) pivotably supported by the rotary body (18), and pivoted by a cylinder (38), to bend the material (1). <IMAGE>
